Assos' warmest winter bib tights, the Uma LL Bib Tights w/Chamois, allow you to ride outside when everyone else is on the trainer! Strategically-placed airBlock 851 panels protect you from wind while insulating key muscles. The AEPD ergonomic cut provides total freedom of movement, while Assos' wicking RX fabric on the thighs and knees keep critical areas warm and dry. You'll also love the Monobib top, stirrups that seal out cold air, and the reflective accents for safety. Plus, these tights have the high-density Assos FI Lady S2 chamois for awesome comfort.
